APPARATUS FOR IRRIGATING AND FERTILIZING GOLF GREENS, ETC.

This invention relates to an improved system and apparatus for irrigating and fertilizing golf greens, base-ball diamonds, lawns, gardens, lawn tennis courts, etc.

One object of my invention is to provide a system of the above kind whereby the soil may be irrigated and fertilized in the natural way, that is to say, by introducing the water at a point where it is first absorbed by the soil and then reaches the roots of the grass.

A further object of my invention is to provide an irrigating and fertilizing system which may be employed with or without a water system.

A still further object of my invention is to provide a system of the character specified which is simple and economical 1n con struction and highly efficient in operation.

With the foregoing and other objects in view that will appear as the nature of my invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts illustrated in the drawings and more particularly pointed out in the appended claims.

In the accompanying drawings which are for illustrative purposes only and are therefore not drawn to scale,

Figure 1 is a plan view illustrating the application of my invention.

Figure 2 is a side elevation of the water distributing tank or receptacle.

Figure 3 is a vertical transverse section thereof.

Figure 4 is a horizontal section taken on line 44 of Figure 3.

Figure 5 is a vertical transverse section, taken through one of the water distributing pipes, and Figure 6 is a detail fragmentary bottom plan view of my invention.

Referring to the drawings for a more particular description of my invention and in which drawings like parts are designated by like reference characters throughout the several views, A designates the central water distributing tank, B the radially disposed water distributing pipes, and C, other water distributing pipes connected with the ends of and circumscribing the radially disposed pipes B, preferably in the form of a square or rectangle. The pipes B and C are formed each, through its length, with a longitudinal series of egress or discharge openings E, the purpose of which will presently appear.

Application filed January 14, 1925, Serial No. 2,4.21.

Renewed March 9, 1926.

In the form of my invention illustrated in Figure 1, the water tank A is preferably in the form of a hollow cylinder open at the top and closed at the bottom by the wall 1. This tank is provided in its body adjacent 1ts bottom with an annular series of radially disposed water distributing pipes B. The tank A is provided above its radially disposed openings 2 with a flat removable false bottom 4- supported in place by the annular shoulder or depression 4 formed in the tank. Said false bottom is provided with a central tubular depending pipe 5 whose lower end 6 fits over the upper end of the hollow boss 7 extending upwardly from the bottom wall 1 of the tank. False bottom 4 and pipe 5 prevent dirt and other foreign matter from collecting in the bottom of the tank A. The false bottom 4 is provided with a central opening 8 and the upper end of the pipe 5 with two or more oppositely disposed openings 9, for convenience in removing the false bottom when water is passing through the hose from tankwagon into tank A. The opening 8 and depending pipe 5 may be used as a holder or receiver for a flag pole or flag staff commonly used on golf greens and the tank A as a putting cup.

Ininstalling my system an excavation is made in the soil to a depth of approximately ten inches and the bottom of this excavation covered with approximately four or five inches of gravel, sand or crushed rock. The water distributing pipes B, C and F are then laid near the top of this gravel and covered with soil. The water passes through the pipes B, C and F into the gravel which becomes saturated and this moisture is then absorbed by the soil covering the gravel and reaches the roots of the grass which is the natural way to irrigate and fertilize.

In practice, water is supplied to the tank A as required, after first removing the false bottom 4, by means of a hose connected with a tank wagon, (not shown), and then flows into the distributing pipes B, C and F, finally discharging through the openings E into the ground, as hereinbefore stated.

From the foregoing description taken in connection with the drawings, it is thought that the construction, operation and advantages of my invention will be readily understood without requiring a more extended explanation.

Having described my invention, what I.

claim as new and desire to secure by Letters Patent is 1. In an apparatus of the character specified, a centrally disposed water tank water distributing pipes communicating with the interior of the water tank, a false bottom in the water tank above the adjacent ends of the water distributing pipes, said false bottom provided with a transverse pening and supporting means for said false bot-tom.

2.1112111 apparatus of the character specified, a centrally disposed water tank, water distributing pipes communicating with the interioriof the vwatertank a false bottom provided with a transverse opening mounted in the water tank above the adjacent ends of thewater distributing pipes and a pipe depending from said false bot-tom, said last mentioned pipe provided in its upper end with a plurality of transverse openings.

3. In an apparatus of the character specitied a centrally disposed water tank, water distributing pipes conununicating with the interor of the water tank, a false bottom provided with a central transverse opening mounted in the water tank above the adjacent ends of the water distributing pipes, a centrally disposed pipe depending from said false bottom and provided in its upper end with a plurality of transverse openings and an annular shoulder formed by a depression in the tank and forming a seat or openingfor the edge of the false bottom.

In. testimony whereof he atlixes his signature.
